“…Cis(c) -MUFAs represented 99.7% of MUFAs, with oleic (9 c -18:1), palmitoleic (9 c -16:1) and ascleptic (11 c -18:1) acids being the most abundant. Trans (t) -MUFAs have not been generally reported in horse meat studies [ 6 , 8 , 62 , 66 , 67 ] as it is known that their content is low compared to ruminant products. The low accumulation of these FAs in equids is related to their digestive physiology [ 12 , 13 ].…”

A full-randomized block design was used for the study of the FA composition and meat quality parameters, considering ageing time as a split-plot factor. Chemical and fatty acid composition of steaks (longissimus thoracis and lumborum muscle) from 15 month old semiextensively reared Hispano-Bretón horses were characterized (day 0), and the effect of vacuum ageing (0, 7, 14 and 21 days) on several meat quality parameters (pH, instrumental color and texture and cook loss) was determined. The average fat content of horse loin was 3.31%, and the n-3 polyunsaturated fatty acid content, although higher than in ruminant meats, suggested that the finishing on a high-grain diet limited muscle n-3 accumulation. Results revealed that ageing affected all meat quality measurements; color started to turn brownish at 14 days of ageing, with a decrease in redness but not in yellowness. Tenderness improved during the first two weeks, and the Warner-Bratzler shear force scores showed that meat aged for 7 days could be considered as ‘intermediate tender’. Under the present study conditions, an ageing period between 7 and 14 days is recommended for an optimum horse meat quality.

“…The muscle tissue of the horses we studied contained equal proportions of SFAs, MUFAs, and PUFAs, which corresponded to the minimum SFA values and the average MUFA and PUFA values available in the literature. Similar to the Yakutian horses, horses that were fed on the native grass pasture had the same percentages of SFAs, MUFAs, and PUFAs, as well as high percentages of 18:3n-3, in subcutaneous adipose tissue [54]. The total FA content of the subcutaneous adipose tissue of the Yakutian horse corresponded to the high values known for horses, varying between 457 and 904 mg/g wet weight [53,54].…”

For the first time, seasonal changes in the content of total lipids (TLs) and phospholipids (PLs) were studied in fodder plants growing in Central Yakutia—a perennial cereal, smooth brome (Bromopsis inermis L.), and an annual cereal, common oat (Avena sativa L.). Both species have concentrated TLs and PLs in autumn under cold hardening. In addition, a significant increase in the content of fatty acids (FAs) of B. inermis was observed during the autumn decrease in temperature. The Yakutian horses, which fed on cereals enriched with nutrients preserved by natural cold (green cryo-fodder), accumulated significant amounts of 18:2n-6 and 18:3n-3, the total content of which in cereals was 75% of the total FA content. We found differences in the distribution of these two FAs in different tissues of the horses. Thus, liver was rich in 18:2n-6, while muscle and adipose tissues accumulated mainly 18:3n-3. Such a distribution may indicate different roles of these FAs in the metabolism of the horses. According to FA content, meat of the Yakutian horses is a valuable dietary product.

“…Both lipid fractions were dried under a gentle nitrogen stream at 40 °C and stored in − 80 °C freezer. Dried lipid fractions were derivatized using a previously described method 15 with modifications 16 . Lipids were saponified with aqueous 10-N KOH and methanol at 55 °C for 1.5 h. Liberated fatty acids were trans-esterified with 24-N H 2 SO 4 and methanol for 1.5 h at 55 °C for 1.5 h. Fatty acid methyl esters (FAME) were extracted in hexane and stored at − 20 °C for GC-MS determination.…”

The objective of the current study was to determine the fatty acid composition of sperm from Holstein bulls with different freezability (Good and Poor; n = 12). Fatty acids were extracted from frozen sperm in 1:2 (v/v) chloroform–methanol solvent, fractionated into neutral and polar fractions, and composition determined by gas chromatography–mass spectrometry. Thirty-four fatty acids were quantified and their concentrations and percentages within each lipid fraction were calculated. Overall, saturated fatty acids (SFA) were predominant, accounting for 71 to 80% of fatty acids in neutral and polar lipid factions. There were marked differences in fatty acid composition between the lipid fractions (P < 0.001). The branched chain fatty acid (BCFA) concentration (15 to 18 µg) was almost twice as much as polyunsaturated fatty acids (PUFA) concentration found in the polar lipid fraction (8 to 9 µg; P < 0.001). Sperm with different freezability phenotypes only had a few differences in 22:0, 18:1 cis 9, and 14:0 13-methyl fatty acids (P ≤ 0.011). These results are significant because they reveal key understandings of fatty acid composition of sperm membrane and lay a foundation for the manipulation of membrane integrity, fluidity, and stability to advance the assisted reproductive technologies.
